Your on the West side of the island where the waters are calm most of the times. September is the height of the hurricane season but your chances of being hit are rare.
Less then a mile south there's a beach bar that's interesting with a fun crowd.
Don't miss the Brimstone Fort that was built by the Brits. When they finished the fort all the cannons had to be brought up and mounted.
Well the French attacked them and took over before they could get them up. While at the fort you'll see the island of St Eustatius which has a volcano in the center and looks like something out of a Jules Verne's movie. Interesting.
